WASHINGJIIACHINE.

Speeication of Letters Patent.

Patented Mar. 30, 1915.

Application led September 28, 1914. Serial No. 863,955.

To all Iwhom it may concern.'

13e it known that I, HENRY C. S'raMM, a citizen of the United States of America, re siding at Mechanicsburg, in the county of Cumberland and State of Pennsylvania, have invented certain new and useful I mprovements in lVashing-Machines, of which the followin is a specification, reference being had t erein to the accompanying drawing.

This invention relates to certain new and seful improvements in washm machines nd more particularly to that c ass of ma- Efchines known as pounders; the object being to provide a machine in which a supplemental tub is mounted upon spring supports to receive the clothes to be washed, which are engaged by a series of vacuum cups carried by a plunger in such a manner that the clothes will be lifted on the up-stroke of the plunger by the vacuum cups so as to cause the water to circulate through the clothes c Another object of the invention 1s to rovide novel means for reciprocatin the p unger whereby the plunger can be a )usted according to the amount of clothes within the clothes rece tacle so that all danger of the mechanism ecoming broken when 1n operation, is prevented. I

Another object of my invention 1s to provide a washin machine with a false bottom under which 1s arranged an inlet having a steam and an air pipe connected thereto by -means of which, steam or air can be fed into the washing machine so as to aid the washin action of the machine.

Anot ier object of the invention is to provide a ielding plunger to reduce the jar on the rivin mechanism.

Other and urther objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the ap ended claims.

n the drawings-Figure 1, is a vertical section through my improved construction of washing machine, showin the driving mechanism in elevation; an Fig. 2, is a detail section through one of the vacuum cups Like numerals of reference refer to like parts in the several figures of the drawings.

In carrying out my invention, I employ a cylindrical rece tacle 1 mounted upon suitable legs 2 in w nich is arranged a perforated false bottom slightly spaced from the bottom of the receptacle 1 on which is mounted a number of coil springs 4 forming a yielding support for a supplemental receptacle 5 which is cylindrical in shape and is arranged concentric with the outer receptacle 1 and is provided with a perforate bottom 6.

The main or outer receptacle 1 is provided with an outlet pipe 7 forming a drain therefor which is controlled by a valve 8 and the bottom .of the main receptacle is provided with an inlet T 9, to one branch of which is connected a steam or air pipe 10 provided with a valve 11 controlling the flow of steam and air therethrough; the other branch of the T being rovided with a water inlet 12 provided wlth a valve 18 through which water is adapted to pass into the receptacle.

In operation, the water and steam are admitted to the receptacle it, of course, being understood that a suitable detergent is emplfved to form suds for washing purposes, an when the clothes are in position within the inner receptacle 5, they will be held submerged within the washin iiuid so that they can be readily acte upon by the pounder, as will be later described.

Extending out from opposite sides of the outer receptacle 1 are spaced arms 14 and 14 the tub being also provided with tubular guides 15 in whlch are mounted rods 1G and 17 which are connected at their upper ends to a cross lbar 18, said cross bar being provided with sockets 19 at its ends to receive the rods 16 and 17 in which said rods are secured by set nuts 20, as clearl shown, in order to allow the cross bar to e detached when desired.

Adjustably mounted on the rods 16 and 17 between the respective arms are sleeves 21 provided with stud pins 22 to which are pivotally connected pitman rods 23 which are connected at their opposite ends to wrist pins 24 secured to drive Wheels 25 mounted upon a drive shaft 26 mounted in suitable bearings 27 extending from the bottom of the rece tacle 1; said drive shaft being provided with a drive pulley 28 which is adapted to be driven by a belt from the power shaft. It will be seen by this construction that when the drive shaft 26 is revolved, the cross bar 18 will be reciprocated through the ptmnn rods and guido rods.

The bnr 18 is provided with a centrally throuded bearing 20 in which is mounted the threaded upper end 3() of a plunger 3l,

said plunger rod being providedfwith; a-

into a sleeve 33 which is provided with a head 3l fitting snugly within the inner receptacle 5; said sleeve beingprovided.: with oppositely disposed slots 35 tliroughwhich extends a pinBG carried bythe plunger in order to allow the plunger rod to slide within the sleeve; the plunger rodbeing surrounded by a coil spring 37 as clearly shown, forming a. 'ieldin' connection between the plunger rody and punge: head 34 in order to prevent the same from beingin'ured when the saine is reciprocated through the driving mechanism. By providing a yielding connection at this point,,when a mass of clothes is in posit'io'nnvithinv the inner receptacle, the plunger head 34 is, allowed to yield when brought into engagement with the mass, so as to prevent injur `to the drivin mechanism. The head 34 1s adapted to ht snugly within the inner receptacle 5 and is provided with a series of vacuum cups 37 secured to the head b screws or rivets 38 as clearly shown in `ig. 2, said cups being provided with .valves 39 so as to allow the washing fluid ltof'pass through the cups on the down-stroke of the plungers and on the-up-strokea partial vacuum is created therein so as todraw. the clothes within the inner receptacle,- upwardly with the plunger, whereby'the, clothes are subjected to a pounding, action as well as to the agitation caused by thel clothes being lifted up and down within the receptacle.

From the foregoing description it will be seen that I have provided a washing machine in which the clothes to be-washed are supported in a yieldingreceptacle and are engaged by a yielding plunger so as to prevent injury to the drivingmechanism and at thesame time to impart an agitative movement thereto. It'will'also be seen that in -rinsin the clothes, air can be injected into the liqui withinthe receptacle and that. by draining the receptacle, the clothes can be wrung.

I claim:

l. A washing machine, comprising a receptacle, guides formed on said receptacle,

'a threaded portion working rod,va,s1eeve slidably mounted upon said 60 plunger rod, a spring surroundin said plunger rod between said sleeve an cross bar, a head carried by said sleeve, and means for reciprocatingrsaid guide rods.

2. In a washing machine, the conihinatenwith'a receptacle, cfa guide rod mounted to each side of said receptacle, a cross bar having a centrall threaded bore, a plunger rod provided wit 1 a threaded portion workinn' 1n saidA bore, a hand-wheel carried by said plunger rod for revolving said plunger rod within said bore to adjust the position thereof, a head slidably carried by said plunger rod, and means for reciprocatin said idel rods;

3. E a washingmachine, the combina tion with a receptacle', of spaced arms projecting outwardlytherefrom provided with tubular ides, rods slidably mounted in said gui es, a cross bar connecting the upper ends of said rods an inner receptacle arranged within the inst-mentioned receptacle', a lunger arranged within said inner receptac e, and a lunger rod yieldingly connected to said unger having a threaded portion mounte in the threaded bore of said cross bar, means for turning said plungerl rod within the bore of said cross bar for adjustingthe position of said plunger within the inner receptacle, and means for re- 9| ciprocating said rods.

4. A washing machine, comprising an l outer receptacle having a false bottom, an inner receptacle supported within said outer receptacle, a plunger working within said 9 inner receptacle, a plunger rod having a slidable 'connection with said plunger, a cross-bar. in whichjsaid plunger rod is adi justably mounted, and meansfor reciprocating said cross bar.. 1

In testimony whereof I hereunto aiix my signature in the lpresence-of two witnesses.
